Trigger finger is a condition where one finger gets stuck in a bent position. The term trigger finger was referenced due to your finger bending or straightening with a snap, like a trigger being pulled and released.
Trigger finger (also known as stenosing tenosynovitis) arises when inflammation narrows the space within the sheath that surrounds the tendon in the affected finger. In severe cases, your finger might become locked in a bent position.
Trigger finger is common in those who work or hobbies involve repetitive gripping. However, the condition is also more common in women and someone with diabetes.
Symptoms of trigger finger vary depending on the severity of the condition, which includes mild and severe conditions. However, there are similar symptoms, which may include:
When experiencing trigger finger, any finger may be affected including the thumb. However, it is possible for more than one finger to be affected at a time and both hands can be affected at once. It is common for this condition to be more pronounced in the morning.

A Tendon is a fibrous cord which attaches muscle to bone. Each tendon is surrounded by a protective sheath. Trigger finger occurs when the affected finger’s tendon sheath becomes inflamed and irritated. When this happens, it interferes with the normal gliding motion of the tendon through the sheath.
Typically, trigger finger occurs from repetitive motion or forceful movement of your finger or thumb.
Below you will the factors that you put you at risk for developing trigger finger:
To properly diagnose trigger finger, your hand surgeon will take a comprehensive medical history which includes prior injuries, information of daily activities, and history of symptoms. During the physical exam, your doctor will ask you to open and close your hand, checking for areas of pain, smoothness of motion and evidence of locking.
Trigger finger treatment varies, depending on the severity of the condition. Some treatments may be more particular than others depending on the diagnosis. In fact, your treatment plan will be made to fit your specific condition.
It is typical for the following to be recommended:
If your symptoms are severe or if conservative treatments haven’t helped, your doctor might suggest:
Percutaneous release. After numbing your palm, your doctor inserts a sturdy needle into the tissue around your affected tendon. Moving the needle and your finger helps break apart the constriction that’s blocking the smooth motion of the tendon.
Surgery: Working through a small incision near the base of your affected finger, a surgeon can cut open the constricted section of the tendon sheath. This procedure is usually done in an operating room.
